Americans eat far less seafood than they do meat, but there's still a long way to go before they chow down on salmon and shrimp in a truly ethical and sustainable manner. Author Paul Greenberg offers facts and tips for making your daily catch a little greener.

For over a century, scientists thought there were only two species of seadragons on Earth. Now a third, the bright-red ruby seadragon, has been discovered — thanks to an enterprising graduate student and some digging through Australia's archives.

A rhino can cost a wildlife park more than $20,000 at auction — but its horn alone can be worth 10 times that much. Many parks and wildlife reserves are buying insurance to protect their investments, and that means an unusual requirement: poisoning the rhinos' horns to ward off poachers.

Who doesn't love a good zoo? The animals, for one. Many of the most popular attractions at zoos are animals like tigers and bears, who are particularly prone to boredom and depression when cooped up. That's why some people want to close traditional zoos and take a different approach.

American chestnut trees are virtually extinct thanks to a blight that ravaged the population in the 20th century. But scientists have been working to create a blight-resistant version of the tree, and they say they've finally succeeded.

Catch a tiger by the tail — and then pop him in a crate and fly him 7,000 miles. Animal lover David Barnes raised nearly $20,000 to relocate a tiger named Phevos from a bankrupt Greek zoo to a new home at an animal sanctuary in California.

The recent agreement between the US and China to reduce greenhouse emissions made headlines — and rightly so. It was a big step for both nations. But, striking a balance between environmental protection and economic ascendance is much more complicated than that. In China especially, it seems, for every step forward, there are often two steps back. Its actions in Tibet are a prime example, according to a newly-published book.

In the battle for physical and sexual supremacy, human tactics haven’t progressed much past the lowly dung beetle. We may have brains capable of producing art and science, and we don’t spend our days hauling around dung (well, most of us don’t, anyway), but otherwise — not much has changed.

Scientists are warning West African villagers to stop hunting bush meat and to stay away from fruit bats as they circle in a possible animal source for the latest Ebola outbreak. The Ebola virus lives in fruit bats, scientists believe, and is threatening communities who are already facing the deadliest Ebola outbreak in history.

If you think drinking and driving is bad, just imagine drinking and flying. That's what some birds in Canada's Yukon territory are doing with the aid of fermented berries, so local animal health officials have prepared a tiny place for the birds to sleep it off.

Just an hour and half from Hiroshima lies the tiny island of Okunojima, probably better known as Rabbit Island. The island is populated by bunnies and tourists feeding those bunnies — but if you look closely you can see remnants of the island's past.

With corals in trouble around the world, researchers are examining the role of smell in telling fish to come to a healthy reef or stay away. That may help scientists find ways to manipulate the smells to help damaged reefs recover.
